What are the coordinates of point B on \overline{AC} such that AB = 1/2 BC
Answer:
C. [tex]B(x,y) = \left(3,-\frac{16}{3} \right)[/tex]
Step-by-step explanation:
Let [tex]A(x,y) = (6,-7)[/tex], [tex]B(x,y) = (x,y)[/tex] and [tex]C(x,y) = (-3,-2)[/tex]. From statement we know that [tex]AB = \frac{1}{2}\cdot BC[/tex], which is equivalent to the following linear algebraic formula:
[tex]B(x,y) -A(x,y) = \frac{1}{2}\cdot [C(x,y)-B(x,y)][/tex] (1)
[tex]B(x,y)-A(x,y) = \frac{1}{2}\cdot C(x,y)-\frac{1}{2}\cdot B(x,y)[/tex]
[tex]\frac{3}{2}\cdot B(x,y) = \frac{1}{2}\cdot C(x,y)+A(x,y)[/tex]
[tex]B(x,y) = \frac{1}{3}\cdot C(x,y) +\frac{2}{3}\cdot A(x,y)[/tex] (2)
Then, the coordinates of point B on AC are:
[tex]B(x,y) = \frac{1}{3}\cdot (-3,-2)+\frac{2}{3}\cdot (6,-7)[/tex]
[tex]B(x,y) = \left(-1, -\frac{2}{3}\right)+\left(4, -\frac{14}{3} \right)[/tex]
[tex]B(x,y) = \left(3,-\frac{16}{3} \right)[/tex]
Which means that correct answer is C.

Find the slope of the line that passes through (2, 1) and (6,2).
Answer:
[tex]\boxed{m = \frac{1}{4}}[/tex]
.
Step-by-step explanation:
Use the form below
[tex]\boxed{\boxed{m = \frac{y_2 - y_1}{x_2 - x_1} }}[/tex]
Where
[tex]m[/tex] is a slope[tex](x_1,~y_1)[/tex] and [tex](x_2,~y_2)[/tex] are the point of the line.
So, the slope is
[tex](2,~ 1) \to x_1 = 2~and~y_1 = 1[/tex]
[tex](6,~ 2) \to x_2 = 6~and~y_2 = 2[/tex]
.
[tex]m = \frac{2-1}{6-2}[/tex]
[tex]m = \frac{1}{4}[/tex]
.
Happy to help:)
Answer:
[tex]\boxed {\boxed {\sf m=\frac{1}{4}}}[/tex]
Step-by-step explanation:
The slope of a line can be found using the slope formula or dividing the change in y by the change in x.
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where (x₁, y₁) and (x₂, y₂) are the points the line passes through.
We are given the points (2,1) and (6,2). Therefore:
[tex]x_1=2 \\y_1= 1\\x_2= 6\\y_2=2[/tex]
Substitute the points into the formula.
[tex]m=\frac{2-1}{6-2}[/tex]
Solve the numerator.
2-1=1[tex]m=\frac{1}{6-2}[/tex]
Solve the denominator
6-2=4[tex]m=\frac{1}{4}[/tex]
This fraction cannot be reduced further, so it is the slope. It can be written as a decimal too:
[tex]m= 0.25[/tex]
The slope of the line is 1/4 (0.25)

Answer:
-5 - 2.3v
Step-by-step explanation:
You want to combine like terms and since two of the numbers have variables, then you can add them both together
4.2v - 6.5 v = -2.3 v
So... -5 - 2.3v or
-2.3v - 5
either or there both same

I need help please I have to finish this
Answer:
Perimeter: 53cm Area: 90cm²
Step-by-step explanation:
For the perimeter, we just add all of the sides of triangle ABC. We have two of them, but we need the length of BC. Using Pythagorean Therom on triangle BCD, we get this length to be 13. So, 13+25+15= 53 cm.
For the area, we can take the area of the big triangle ADB and subtract the area of triagle BCD so that we are left with the area for triangle ABC. Using Area= .5 x base x height, we get that the area of the large triangle is 120cm² and the area of the small triangle is 30 cm², leaving the area of ABC to be 90 cm².
(Note: the formula for area of the triangle only works on triangles with a right angle or triangles were the height and base are perpendicula, so simply doing .5 x 15 x 12 will not work. However, .5 x 15 x 12 does work because it is perpendicular.)
Help. I do not know pls I require assisstance
Answer:
-1 is not in domain
0 and 2 both are in domain.
Explanation:
The radical function must have the domain greater or equal to 0. Here is why.
If we substitute any negative numbers in the equation
[tex]y = \sqrt{x} [/tex]
Then we would get the Imaginary Number, meaning it doesn't exist in Real Number system. That's why any negative real numbers cannot be part of the domain.
But that's for y = square root of x. There are like 4 types of radical function but this one is for example.
The equation in the question is the same type as the example equation.

Step-by-step explanation:
A person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen he sells it at Rs 80 a pair find the gain percent pls do it step by step
Given,
CP of cosmetics = Rs 360 per dozen
SP of a pair of cosmetics = Rs 80
To find,
The gain percent
Solution,
1 dozen = 12 items
CP of 1 cosmetic = 360/12 = Rs 30
SP of 1 cosmetic = 80/2 = Rs 40
Profit = SP-CP
= Rs 40 - Rs 30
= Rs 10
Profit percentage is given by :
[tex]\%=\dfrac{profit}{CP}\times 100\\\\=\dfrac{10}{30}\times 100\\\\=33.34\%[/tex]
So, the profit percentage is 33.34%.

Note: ( if you give me a silly or absurd answer I will report you)
===================================
Work Shown:
First evaluate f(2)
[tex]f(x) = 4x^3-10\\\\f(2) = 4(2)^3-10\\\\f(2) = 4(8)-10\\\\f(2) = 32-10\\\\f(2) = 22\\\\[/tex]
This means g(f(2)) = g(22). We replace f(2) with 22.
Now evaluate g(22)
[tex]g(x) = \frac{3x-4}{2}\\\\g(22) = \frac{3*22-4}{2}\\\\g(22) = \frac{66-4}{2}\\\\g(22) = \frac{62}{2}\\\\g(22) = 31\\\\[/tex]
Therefore, g(f(2)) = 31.
Answer:
D
Step-by-step explanation:
Let's start with f(2)
Substitute 2 as x in f(x)
4(2)^3-10
32-10
22
now take g(22) (f(x) is equal to 22) and substitute x as 22
(3(22)-4)/2
(66-4)/2

An amusement park is considering installing an outdoor ice-skating rink, which costs $950,000. Expenses for operating and maintaining the ice-skating rink are estimated at $2,500 each day it is used. The outdoor skating rink can only be used when the weather is sufficiently cold, so its usage is limited. The US weather service estimates that there is a 50% probability of 80-day suitable weather per year, 30% probability of 100 days per year, and 20% probability of 120 days per year. The operators of the amusement park estimate that during the first 80 days of use in a season, an average of 500 people will skate each day, at a fee of $20 each. If 20 additional days are available, the rink will be used by only 400 people each day during the extra period, and if 20 more days of skating are available, only 300 people per day will use the rink during those days. The management of the amusement park wish to recover any invested capital within three years and want at least a 22% per year rate of return before taxes. Based on before tax analysis, should the outdoor ice-skating rink be installed
Answer:
Yes, the outdoor ice skating rink should be installed.
Step-by-step explanation:
We can reach this conclusion after simulating the profit for each possible scenario made by The US weather service estimates:
For 80-day suitable weather per year:
total invested capital = $950,000 + $200,000 (total operating and maintaining cost) = $1,150,000per day revenue= 500 x $20 = $10,000total revenue per season = $10,000 x 80 days = $800,000total operating and maintaining cost = $2,500 x 80 = $200,000total profit (returns) in a season = $800,000-$200,000 = $600,000per year rate of return before taxes = 52% (total profit / total invested capital *100; $600,000/$1,1150,000 *100 = 52%For 100 days suitable weather per year:
total invested capital = $950,000 + $200,000 (total operating and maintaining cost) = $1,150,000per day revenue= 400 x $20 = $8,000total revenue per season = $8,000 x 100 days = $800,000total operating and maintaining cost = $2,500 x 100 = $250,000total profit (returns) in a season = $800,000-$250,000 = $550,000per year rate of return before taxes = 52% (total profit / total invested capital *100; $550,000/$1,1150,000 *100 = 47%For 120 days suitable weather per year:
total invested capital = $950,000 + $200,000 (total operating and maintaining cost) = $1,150,000per day revenue= 300 x $20 = $6,000total revenue per season = $6,000 x 120 days = $720,000total operating and maintaining cost = $2,500 x 120 = $300,000total profit (returns) in a season = $800,000-$250,000 = $420,000per year rate of return before taxes = 52% (total profit / total invested capital *100; $420,000/$1,1150,000 *100 = 58%Threfore, we notice that the 22% per year rate of return before taxes criteria was met in each of the possible scenarios, making the endeavor worthwhile.

Step-by-step explanation:
if you're wrong its your fault
. Mr. Ahmet, who won a prize of 1 million USD by participating in a quiz show, will
provide a significant return if he uses it in repo, time deposit and bonds. However, careful decisions need to be
made as to which area to invest. If the money is deposited in the bank, the bank pays interest once a month and
pays 16% interest. Mr. Ahmet wants to buy 2 houses, one worth 900000 USD and the other 500000 USD, in the
future, by investing this money in the bank. Accordingly, after how long is it possible for Ahmet Bey to buy these
two houses with the money and income he earned? If you were Mr. Ahmet, how would you advise him to use
this money?
Answer:
See below
Step-by-step explanation:
Mr. Ahmet needs:
(900000 + 500000) - 1000000 = 400000more to have enough money to buy those two houses.
Monthly, he gets interest paid:
1000000*0.16/12 = 13333.33Time to have required amount is:
400000/13333.33 = 30 months = 2.5 yearsWithout taking the deposit he would need time:
1400000/13333.33 = 105 months = 8 years and 9 months to buy two housesHe could wait and use the interest to buy houses provided they will still be available and price remains same.
